Abstract

The invention relates to the technical field of hydraulic drive, in particular to a hydraulic hatchcover opening device applied to a large ship, comprising an active hatchcover, a follower hatchcover and an installation seat arranged at the side of a hatchway, wherein the installation seat is hinged with a turning cover which is fixedly connected with one side end of the active hatchcover, and the other side end of the active hatchcover is hinged with the rear side end of the follower hatchcover; the front side end of the follower hatchcover is provided with a hatchcover idler wheel, and an idler wheel moving rail is correspondingly arranged at the periphery of the hatchway; a first oil cylinder and a second oil cylinder which are provided with oil by a double oil cylinder hydraulic control device are connected between the installation seat and the turning cover; the lower ends of the first oil cylinder and the second oil cylinder are coaxially hinged to the installation seat, and the lower end parts of piston rods of the first oil cylinder and the second oil cylinder are respectively hinged with different connected parts on the turning cover so that the turning cover turns outwards or inwards under the matching action of the double oil cylinders. The device not only lowers the opening height of the hatchcover, but also has little occupation area of the opened hatchcover, compact structure and good use effect.

Description

technical field [0001] The invention relates to the technical field of hydraulic drive, in particular to a hydraulic hatch cover opening device applicable to large ships. Background technique [0002] In the prior art, some large ships have a high opening height and a large amplitude of the hydraulic hatch cover, and the area occupied by the hatch cover is large, which not only affects the safety of the hatch cover opening process and the stability of the ship. It has a certain impact, and it cannot be implemented on some ships with large hatches with small widths on the left and right decks. [0003] Therefore, need carry out new design to the opening mechanism of ship hatch cover. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies of the prior art and provide a ship hatch opening device, which not only reduces the opening height of the hatch cover, but also occupies a small area after the hatch cover is opened, has a c...
